FOR INFORMATION 
THREE SCREWS PUMPS
The three screws pumps are positive displacement rotary pump with axial flow design.
There are only three moving parts. The power rotor is the only driven part that extends outside the case.
The idler screws act also as sealing parts and are turned hydraulically by the fluid being pumped.
Idler screws are also available with magnetic coupling that garantiee which ensures a complete operation without losses.
This is the only reliable solution when it is forbidden to produce any enviromental pollution.
SFO PUMPS SERIES
LUBRICATION – CIRCULATION – FUEL TRANSFER
In SFO pump series the fluid has a uniform axial flow, which allows a minimum pulsation of it and an extremely silent operation.
SFO pump has been designed for the management of not aggressive fluids with enough lubricating propeties.
SFO pumps are perfect for lubrication, circulation and for transfers.

SMT PUMPS SERIES
SCREW PUMPS FOR SILENT APPLICATIONS AND MEDIUM-LOW PRESSURE
SMT series are three screw pumps for industriaal applications at low and medium pressure (80 bar).
SMT pumps are components reilable and low noise for industrial use that requires a pump with long life at low cost.
The SMT is a priming pump assembled in a pump casing.
The three screws rotate inside the pump body and the design of the screws is made to avoid any axial load.

FOTP PUMPS SERIES
LOW VISCOSITY DIESEL AND LOW SULPHUR CONTENT
FOTP pumps series are an advanced version of pumps for diesel fuel, even more performance, and safely, strongly oriented to the solution of new problems
related to the low viscosity and low sulfur content in the new marine diesel fuels (MDO).
The action is meant to meet the needs of the LOW SULPHUR CONTENT market - specific MDO, according to international standard ISO8217/2005.
The pump operates ordinary diesel, MDO, MGO, MDO low sulfur HFO oil, Bunker.
The handles of FOTP pumps is constituted by two pumps driven at the same time or alternatively.
